RESUMO
Anabolic androgenic steroids (AAS) are recommended for therapeutic clinic, but their use has increased in recent decades for aesthetic reasons. No study has evaluated the impact of AAS in the fallopian tube, after treatment and recovery periods. Herein, the aim of study was to investigate the effects of Nandrolone Decanoate (ND), administered in different doses (1.87; 3.75; 7.5 and 15â¯mg/kg) on the ampulla of the fallopian tube in rats, following post-treatment (PT; 15 consecutive days) and post-recovery (PR; 30 consecutive days) periods. The control group received mineral oil. Estrous cycle was monitored daily during both periods and in sequence the rats (nâ¯=â¯8/group/period) were killed. All ND-treated animals showed estral acyclicity during the PT and PR periods, but the histomorphometric changes in the fallopian tube varied according to the ND dose level. The expression of AR, ERα and ERß varied in the nucleus and cytoplasm of epithelial cells. No AR expression was observed in the stroma. The muscle cells exhibited variation in immunostaining. In conclusion, ND promoted histomorphometric and immunohistochemical changes in the ampullary portion of the fallopian tube after treatment and recovery periods in a dose-independent manner.
